C2000 Saturate IQN

Saturate IQ number

Description

This block saturates an input IQ number to the specified upper and lower limits. The returned value is an IQ number of the same Q value as the input.

Note

The implementation of this block does not call the corresponding Texas Instruments^® library function during code generation. The TI function uses a global Q setting and the MathWorks^® code used by this block dynamically adjusts the Q format based on the block input. See Using the IQmath Library for more information.
